1080p
Video game consoles such as Microsoft's Xbox 360 and Sony's PlayStation 3 are able to display 1080p through Component video, HDMI. The Xbox 360 Elite was the first Xbox with an HDMI port (something not found in the machine's initial design) but now all newly produced Xbox 360 consoles include the port as standard. The internal hardware scaler inside Xbox 360 means it can output 1080p regardless of the native resolution of the game being played or video being watched. Very few games boast a native resolution of 1080p (examples are Sega's Virtua Tennis 3, as well as downloadable offerings on the PlayStation Store such as LocoRoco and Super Stardust HD). Many more PS3 games support 1080p resolutions despite not natively rendering in that resolution (such as Grand Theft Auto IV, which will display in 1080p but has a native resolution of 1120 x 630p). However there are more PS3 games that runs in 1080p natively than Xbox360 (such as Halo 3 and Ninja Gaiden 2 which have a native resolution of 1152 x 640p and 1120 x 585p respectively). In the beginning Sony disabled the PS3's internal upscaler, possibly to make developers optimize their games more to run natively to a higher resolution. Since the PS3's release, Sony has enabled the system's internal upscaler via a firmware update.

Ability of the eye to see 1080p
A person's ability to distinguish small details is described by visual acuity. When individual pixels are barely resolvable, increased resolution brings no benefit for the viewer unless the viewing distance can be shortened or the display enlarged. Thus for 1080p television viewing there is a minimum size to distance ratio to see a benefit. The ability of the eye to resolve 1080p content also depends on the amount of contrast in the picture. For optimum viewing it is recommended to sit back approximately three times the height of the screen.[7][8][9]
